Timing Belt Replacement

Meet some of our expert Lexus mechanics

Ben was top notch: Courteous, friendly, and professional. He changed out a timing belt and serpentine belt, plus secured a mirror that was flopping in the wind, all in about 4 hours, and didn't charge for the mirror. I'll ask for him next time I need service.
The site itself is a Godsend. My elderly mother had taken her Lexus to several places and been quoted over $2,000 at each to change her timing belt. I knew that was high. Through Your Mechanic, we got both her timing belt and serpentine belt changed for $710.83. How could I not want to use this service again?!

Jeff was very friendly and answered any questions I had. We discussed what services I should have done in the future and the value of using factory parts for certain items. ie spark plugs. Jeff made sure to clean up after himself and kept my garage clean.

All about Timing Belt Replacement

The timing belt is a rubber belt located in the engine compartment behind the drive belts. Its job is to keep the crankshaft in sync with the camshaft(s), ensuring the proper timing and operation of the engine valves and therein, the engine.

When replacing a timing belt, also replace the water pump, tensioner, and pulleys.

If the pulleys and tensioners should fail after only replacing the belt, it can cause valve or piston damage and lead to more expensive repairs, in order to have the engine run properly. It is therefore essential to replace the whole set.

We only replace the water pump if it is driven by the timing belt (true for 60% of the cars).

Ignoring the replacement of a timing belt as a part of scheduled maintenance, could result in major engine failure down the road. You should not wait for your timing belt to break, it must be serviced regularly.
